Property Value

Type	Description

Remarks

• EditorFilterMode — specifies whether values in the drop-dow window should start with or contain the entered text.
• EditorFilterComparisonType — specifies how to compare the entered text with values in the drop-down list.

To specify the list of available values, use the ItemsSource collection.
